Description

The TMP390 evaluation module (EVM) is a plug-and-play system to test and evaluate the TMP390 analog temperature switch. TMP390EVM features resistor-programmable inputs for the dual-channel switch with both hot and cold trip settings.

The EVM can be plugged into a USB port to supply power to the board, or may be powered externally.

Trip tests are available for both channels utilizing the onboard push buttons with LED indicators at the output of the TMP390 to show when the sensor trips. The sensor is located on a breakout board that can be separated from the main PCB board to allow for prototyping.

TMP390EVM does not require any calibration or software programming, as the trip points are set physically with resistors, which may be replaced to test at other temperature thresholds.
